74LS Datasheet PDF / TI –

Quoth Christian Bjelle at The Group moderators are responsible for maintaining their community and can address these issues. The bases of the bipolars would be connected to the outputs of the 74LS via resistors. I would then have bipolar NPN transistors with the collectors connected to 12V via resistors.

I amy have misundertood you completely, but 774ls145 think there is a much simpler solution.

Do I need to put an inverters between the 74LS and the bipolars? So, for the meantime, it looks like my original plan stands, minus the base resistors thanks John! You can skip the bipolar alltogether, 74sl145 connect your pull-up directly to 12V.

74LS145 Datasheet

If the 74LS will sink enough current, I think you should be able to meet your needs with a cascode stage, and this will only require one transistor and maybe one resistor per output. If you want to used the FET, substitute the source for the emitter, the gate for the base, dataheet the drain for the collector.

That makes my life much easier, although I will have to check on the manufacturer of the devices that I have to make sure that they have the higher voltage tolerance. This is certainly a technique to apply for other applications I datashest a LOT to learn in the analogue daatsheet I think that we would have the same issue that John pointed out — the control signals are inverted and still need to be flipped before they get to the output device.

Are you sure you wish to delete this message from the message archives of neonixie-l groups. Since the outputs of the LS are active low when selected, and the FET gate is active high, the transistor as 74ls14 show it in your picture gives the inversion you need. The gates of the HV drivers would be connected to collectors of the bipolars. Thanks for your help on this guys! Subject of the new topic: Your email is included with the abuse report.
